Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Die ursprünglich von Jöubert angegebene Methode zur Bestimmung der Wechselstromcurven, sowie die anderen auf dieser Methode sich aufbauenden Abänderungen benutzen Contactvorrichtungen, welche bei jeder Umdrehung einen Stromkreis, durch welchen eine periodische Strömung verläuft, während einer gewissen Zeit dieser Periode schliefsen, so dafs es möglich ist, mit Hülfe eines in diesen Stromkreis eingeschalteten Mefsinstrumentes den zu dieser Zeit bestehenden Zustand der Strömung zu prüfen. Aber bei keiner dieser Contactvorrichtungen ist die Möglichkeit gegeben, die Dauer des Stromschlusses veränderlich zu machen.The one originally specified by Jöubert Method for determining the alternating current curves, as well as the others on this method developing changes use contact devices, which with each revolution a circuit through which a periodic flow runs, during a certain Close during this period, so that it is possible to close them with the aid of a measuring instrument connected to this circuit Check the current state of the current at this time. But none of these contact devices it is possible to change the duration of the power supply.

Dieser Zweck soll nun bei vorliegender Erfindung dadurch erreicht werden, dafs zwei in derselben Umdrehungsebene an einer Scheibe S isolirt befestigte Contactbürsten A und B durch ein vermittelst der Welle C in Umdrehung versetztes isolirtes Stromschlufsstück D in dem Augenblicke mit einander in metallische Verbindung gesetzt werden, in welchem die eine Bürste A dasselbe zu berühren beginnt, während die andere B dasselbe ' gerade verläfst.This purpose is now to be achieved in the present invention by, in the same rotation plane on a disc S insulated fixed contact brushes A and B by means of the shaft C in turn shifted isolirtes Stromschlufsstück D at the moment with each other in metallic compound DAF set two, in which one brush A begins to touch the same thing, while the other B brushes the same thing straight away.

Da die eine Bürste B verschiebbar angeordnet ist, so läfst sich die Dauer des Stromschlusses damit innerhalb gewisser Grenzen veränderlich machen.Since the one brush B is arranged to be displaceable, the duration of the current circuit can thus be made variable within certain limits.

Patent-Ansprüche:Patent Claims: ι . Rotirende Contactvorrichtung für elektrische Mefsapparate zur Aufnahme von periodischen Curven nach der Methode von Jo ubert, bei welcher während einer Umdrehung durch eine Contactscheibe nebst Contactbürsten ein Stromkreis nur einen Augenblick geschlossen wird, dadurch gekennzeichnet, dafs zwei in derselben Umdrehungsebene liegende Contactbürsten durch ein Metallsegment in dem Augenblick mit einander verbunden werden, in welchem die eine Bürste das Segment zu berühren beginnt, während die andere dasselbe gerade verläfst.ι. Rotating contact device for electrical measuring devices for receiving periodic Curving according to the Jo method, in which during one revolution a circuit is only closed for a moment by means of a contact disc together with contact brushes, characterized in that that two contact brushes lying in the same plane of rotation through a metal segment at that moment in which one brush begins to touch the segment while the other does the same just running. 2. Eine Ausführungsform der vorbezeichneten Anordnung, bei welcher eine sehr feine Einstellung der Zeitdauer des Stromschlusses dadurch ermöglicht wird, dafs die eine Contactbürste verschiebbar angeordnet ist.2. An embodiment of the aforementioned arrangement, in which a very fine Setting the duration of the current circuit is made possible by the fact that the one Contact brush is slidably arranged. Hierzu 1 Blatt Zeichnungen.1 sheet of drawings.
